The flame retardant work of polyolefin materials has always been a challenge in the industry. Herein, we report a triazine charring agent (TM) containing hydroxyl and triazine ring. Combined with ammonium polyphosphate (APP), TM was applied to prepare flame retardant thermoplastic polyolefin (TPO) composites. The results of thermogravimetric analysis (TGA) test show that TM has high initial pyrolysis temperature and retention rate of char residue at high temperature. The UL-94, limit oxygen index (LOI) and cone calorimetry tests (CCT) were used to characterize the flame retardancy of TPO composites. The UL-94 V-0 rating and LOI value of 29.2% are achieved with a loading of 9.17 wt% flame retardant (TPO-3). In particular, the fire performance index (FPI) associated with the flashover time also increases to 0.037 m2s/kW compared with TPO (0.030 m2s/kW). The synergistic effects of APP/TM were investigated in depth. The results show that APP/TM system forms a dense and continuous char layer on the surface of TPO during combustion, which effectively insulates the substrate from heat and oxygen erosion. Additionally, APP/TM system also plays a weak but important flame retardant role in the gas phase, including quenching effect of phosphorous compounds and dilution effect of non-combustible gases.

含羟基和三嗪环的三嗪成炭剂的合成及其在热塑性聚烯烃中的阻燃应用
聚烯烃材料的阻燃工作一直是业界面临的挑战。在此，我们报道了一种含有羟基和三嗪环的三嗪炭化剂 (TM)。结合聚磷酸铵（APP），将TM用于制备阻燃热塑性聚烯烃（TPO）复合材料。热重分析(TGA)测试结果表明，TM具有较高的初始热解温度和高温下炭渣的保留率。UL-94、极限氧指数 (LOI) 和锥形量热测试 (CCT) 用于表征 TPO 复合材料的阻燃性。UL-94 V-0 等级和 29.2% 的 LOI 值是在 9.17 wt% 阻燃剂 (TPO-3) 的负载下实现的。特别是，与闪络时间相关的防火性能指数（FPI）也增加到 0.037 m 2s/kW 与 TPO (0.030 m 2 s/kW) 相比。深入研究了APP/TM的协同效应。结果表明，APP/TM体系在燃烧过程中在TPO表面形成致密且连续的炭层，有效隔绝了基体的热和氧侵蚀。此外，APP/TM体系在气相中也起到了微弱但重要的阻燃作用，包括磷化合物的淬火作用和不燃气体的稀释作用。
